Excimer laser
A laser that emits very concentrated light in the ultraviolet (UV) region of the spectrum.

Excimer Laser Angioplasties
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: a) laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; b) balloon angioplasty immediately following laser angioplasty; or c) laser energy transmitted through angioplasty balloons that contain an internal fiber.

Excimer Laser Angioplasty
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: a) laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; b) balloon angioplasty immediately following laser angioplasty; or c) laser energy transmitted through angioplasty balloons that contain an internal fiber.

Excimer Laser Keratectomies
A type of refractive surgery of the cornea to correct myopia and astigmatism, using an excimer laser. An excimer laser is a laser containing a noble gas, such as helium or neon, which is based on a transition between an excited state in which a metastable bond exists between two gas atoms and a rapidly dissociating ground state. The extremely precise laser light reshapes the surface of the cornea without making an incision. This procedure can reduce much higher degrees of myopia than radial keratotomy (KERATOTOMY, RADIAL), although it generally takes longer for vision to clear. (From In Focus 1994;1(2):3 and McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p675)

Excision
1. Surgical removal, as in the excision of a tumor. 2. The removal as if by surgery, as in base excision repair.

Removal of only enough breast tissue to ensure that the margins of the resected surgical specimen are free of tumor.

Excision Repair
The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as ""dark repair"" because they do not require light.

Excision Repair, Nucleotide

Excision, Lymph Node
Surgical excision of one or more lymph nodes. Its most common use is in cancer surgery. (From Dorland, 28th ed, p966)

Excision, Prophage
The mechanism by which latent viruses, such as genetically transmitted tumor viruses or prophages of lysogenic bacteria, are induced to replicate and are released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell lipopolysaccharides, glucocorticoid hormones, halogenated pyrimidines, ionizing radiation, ultraviolet light, and superinfecting viruses.

Excision, Tubal
Surgical interruption of the fallopian tube during laparotomy or in the context of pelvioscopy.

Excisional
Pertaining to the act of excision, of removal by surgery. An excisional biopsy is one in which the lesion is removed by the biopsy.

Excisional biopsy
A biopsy in which an entire biopsy in which an entire lesion, is removed. A excisional biopsy is in contrast to an incisional biopsy in which only a sample of tissue is cut into (incised) and removed.

Excitatory Amino Acid Receptor
Cell-surface proteins that bind glutamate and trigger changes which influence the behavior of cells. Glutamate receptors include ionotropic receptors (AMPA, kainate, and N-methyl-D-aspartate receptors), which directly control ion channels, and metabotropic receptors which act through second messenger systems. Glutamate receptors are the most common mediators of fast excitatory synaptic transmission in the central nervous system. They have also been implicated in the mechanisms of memory and of many diseases.
